mina [271]

For this case, the first thing we must do is define variables:

x: students of group 1

y: students of group 2

We now write the system of equations that models the problem:

x + y = 28\\y = 2x + 4

Solving the system by substitution we have:

x + (2x + 4) = 28\\3x + 4 = 28\\3x = 28-4

3x = 24

x = \frac{24}{3}\\x = 8

Then, the value of y is given by:

y = 2 (8) +4\\y = 16 + 4\\y = 20

Answer:

8 students of group 1

20 students of group 2

Answer:

m∠K = 36°

m∠L = 54°

m∠M = 90°

Step-by-step explanation:

         A triangle's angles add up to 180 degrees. We will add together all the angles and set them equal to 180. Then, we will solve for x. Lastly, we will solve for the angle measurements.

-> The little "box" in angle M means that it is equal to 90°

90° + (2x + 42)° + (4x + 12)° = 180°

90° + 42° + 12° + 2x° + 4x°= 180°

144° + 6x°= 180°

6x° = 36°

x = 6°

[m∠K]

4x + 12

4(6) + 12

36°

[m∠L]

2x + 42

2(6) + 42

54°
